The Red Bulls have gone 17 seasons without a title, including the years they were called the MetroStars, but the fact they come into the season’s second-to-last game tied with Portland atop the standings — holding the tiebreaker and control of their Supporters’ Shield destiny — tells coach Mike Petke don’t fix what isn’t broken.

“Listen, we’ve obviously done something right as a team this year to be in the position that we’re in,” Petke said after Wednesday’s practice. “Why change with what has done well for this year? It hasn’t been perfect, but it has put us in the spot. So, it’s all about just keep going. The intensity and the buzz naturally on their own have stepped up a bit this week.’’

With just two games left, the Red Bulls can clinch the Supporters’ Shield — for the best regular season record in the MLS — if they win both, their first meaningful hardware. After the Revolution game, Petke openly talked about resetting the goals, having clinched a playoff berth and now taking aim at breaking the club’s trophy drought.

Petke also said he hasn’t been beating the players over the head about the importance of winning the next two. He hasn’t had to.

“Initially following the New England game… I let certain words slip out of my mouth and talk about our next goal. We haven’t talked about it since,’’ Petke said. “They know. They’re grown-ups. They’re intelligent. They know where we are in the standings.

“They’ve probably have done a little bit of math in their heads to figure things out. They know what’s on the line. So I don’t need to harp on it every day. These guys have shown me this year that they’re professional enough and mature adults and handle situations. I don’t need to keep reinforcing it.’’

So Petke gave the Red Bulls off the long Columbus Day weekend, and now they will prepare to play in Houston on Sunday (4 p.m., MSG) without making any rash or glaring changes. After all, what they have been doing has gotten them closer to the Supporters’ Shield than they ever have been.

“That is how we prepare for every game and how we have gone about our practices. There’s no need right now to change things up,’’ said Petke said. “We gave them the days off a little differently this time. Coming back in, we have five full days before the game and we went about business the way we usually do.’’

The last time the organization was this successful was when the then-MetroStars lost the U.S. Open Cup final 1-0 to Chicago 10 years ago under Bob Bradley and lost the MLS Cup final to Columbus in 2008 under Juan Carlos Osorio. With two wins, Petke has a chance to become the first coach to ever bring meaningful silverware to this club, and that’s a boat he doesn’t plan to rock.
